Creating a payout
When creating a payout, there are two possible flows:
- You already know the crypto address of the destination of the payout and can enter it on the API call.
- You don't know the crypto address of the destination of the payout, and will redirect the user to the hosted page to collect it.
In the same way as the payments workflow, you will be provided with a redirect URL to collect the details if necessary. For this guide, we will presume you have the address already.
Validating the crypto address
If integrated directly with our API, before making a payout, it is recommended to validate the crypto address with the Validate address endpoint. This checks that all required data is present in order achieve a successful payout. This improves end user experience by providing this feedback ahead of creating the payout. If you're using the hosted page the address will be validated when inputted by the end user.
For example, tag
is required for XRP payouts to exchanges, ensuring the funds are allocated to the correct customer.
If the address is invalid the payout request will fail and you'll see an error like the following:
{
"errorList": [
{
"parameter": "payOutInstruction",
"code": "invalidPayout",
"message": "Invalid Instruction for Payout"
}
]
}
Setting a unique reference
Make sure you are setting a unique reference for the payout, otherwise you'll see an error like the following:
{
"errorList": [
{
"parameter": "reference",
"code": "unique",
"message": "Duplicate Reference"
}
]
}
Making the request
Here's an example payout request using the Create payment endpoint.
curl --location 'https://api.sandbox.bvnk.com/api/v1/pay/summary' \
--header 'Content-Type: application/json' \
--header 'Authorization: Hawk id="vbfc61D890wg6LAAVbkR11qP9O6cXeMNmKWgcUNZaOHPiQeebp9cl6h02tWv84R8", ts="1728648264", nonce="uBmULV", mac="Z5hY60DlvCVq/WpIEXN4OhAlg1FwZb6DcDJP6TVGHjI="' \
